Well anybody from your class who is watching this thread, including your instructor, will know by now that you haven't the foggiest idea what you are doing. And about the worst thing they could do would be to copy your validation code. Any of it.
Even the stuff you said was working was maybe 3 times more complex than it needed to be and had errors and holes one could drive a semi-truck through.
The only thing you are accomplishing by not showing your code is making it harder for me (and others, if anybody else hasn't given up by now) to fix it for you.
The best thing you could do at this point would probably be to scrap all the code and start over. Hopefully having learned something better by now.
Here's one hint: There's almost surely NO REASON AT ALL for you to be using document.getElementById( ) in any of your validation code.
An optimist sees the glass as half full.
A pessimist sees the glass as half empty.
A realist drinks it no matter how much there is.
